CHURN MECHANISM.

SPECIFICATION forming part of Letters Patent No. 271,705, dated February6, 1883.

Application filed September 27, 1882. (No model.)

To all whom it may concern Beit known that we, JosEPH W.HELDRETH andEVERETT W. UMBERGER, Citizens of the United States, residing atWytheville, in the county of Wythe and State ot' Virginia, have inventeda new and useful Churn, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to churn-motors or to devices and mechanism foroperating churns,

' and has for its object to pro\ide a simple and efficient device thatwill readily impart either a rotary or vertically reciprocating motionto the dasher-staff of the churn.

'1 In the drawings, Figure .l is a perspective view; Fig. 2, a verticallongitudinal sectional View; Fig. 3, a like transverse View; Fig. 4, aperspective view of the device prepared for reciprocating motion.teferringto the drawings, A designates the base, which is provided withtwo parallel perpendicular uprights, B B, provided with an intermediatecross-piece,(),aboutmidway,and having their top ends bifurcated, orformed with open slots 1). The bottoms of slots D D may be provided withcushions E, and their tops receive the end tongues F of a removablecross top piece, G, said tongues F F being held in place by transversepins or bolts 1 H, passing through perforations in uprights I is atransverse block, having end tongues J J. which work in slots D D.

K is the cylindrical dasher-staft', which has a bearing, L, in toppit-cc, G, bearing M in cross-block 1, and bearing N in cross-piece O,and is provided above the latter with a shoulder, 0, on which rests ahorizontal balancewheel, P. In shoulder O is arranged a pert'o- 0ration, Q, through which passes a cord,R, the ends thereof being passedup and through wheel P and secured in or to vertically-moving block I.The cross-block I is operated by a lever, S, pivoted to a standard, T,in rear of the uprights B B. The end of lever S is bifurcated, and thearms U U thus formed embrace stafi K under block I. The top block, G,has a dovetailed groove, V, arranged over the perforation L, in whichworks a dovetailed plate, W, to prevent lateral displacement of thestaff K. Groove V and plate W are preferably wedge-shaped to enable thelatter to firmly bind in the groove.

To the lower end of rod K is secured the ohurn-dasher X, a rotarywheel-dasher, Y, such as shown in Fig. 4, being preferred when areciprocating motion is used.

The operation and advantages of myinvention will be readily understood.\Nhcn block I is down the cord It will he wound spirally around rod K inone direction. Then, by lowering lever S, the block 1 is elevated, whichcauses the cord to unwind, thus rotating the balance-wheel and dasherrod orstatf. The momentum thereof serves, when the cord is unwound, towind it round the stafi'again in the contrary direction to what it wasbefore, and thus bring down block I ready for the next stroke of thelever. By this means the dasherstaff is alternately revolved in bothdirections. For a reciprocating motion the plate \/V is removed and thecord R is drawn tant to secure the block I down-as close as possible tothe balance-wheel. Then, when lover S is raised to elevate block I, thesaid block lifts the balance-wheel and dashenstafl. As soon as the holdon lever S is released the weight of the balance-wheel causes the statfto fall.

We claim as new 7 The combination of the uprights,- thevertically-moving block I, the dasher-stafi having a horizontalbalance-wheel, the connectingeord extending down from block I, and thecross top piece, G, having central vertical bearing, L, for thedasher-rod, over which bearing L is formed a groove, V, covered by aremovable plate, W, as set forth.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence oftwo witnesses.
